A Houston jury Tuesday convicted Texas financier R. Allen Stanford on all but one of the charges he faced for allegedly bilking investors out of more than $7 billion in one of the largest Ponzi schemes in U.S. history.

Questions:

1. Why, if Allen Stanford faces up to 20 years in prison for the most serious charges but could he be imprisoned for much longer?

2. How did Mr. Stanford separate the investors from their money and when did the government shut down the scheme?
